Referring to Fig. 1-Fig. 3, moving beam 4 remains on a high position, the locking wrench 8 being connected with air motor 7 is rotation status not, when be loaded with the transport trolley of swage sandbox be pushed to device under time, now case card bolt 10 is in unscrewing state, lift cylinder 5 starts to drive moving beam 4 to decline, guide post 6 plays and leads and maintain the effect that moving beam 4 steadily declines in this process, all there is case card bolt 10 front and back of transport trolley as can be seen from Figure 2, therefore, above case card bolt 10, locking device is all installed, the quantity of the quantity of locking device and case card bolt 10 matches, guarantee that whole device turns round simultaneously, improve automaticity.
Referring to Fig. 4, structural representation for the A-A in Fig. 3, when rotating shaft 86 relatively rotates with respect to sleeve pipe 83, steel ball 851 is forced to extrude the hemispherical cancave cambered surface 861 of rotating shaft 86, again under the effect of the second Compress Spring 852, next cancave cambered surface 861 of jacking, thereby the intermittent moment of torsion of countershaft 86 output, with further clamping screw.
Combined type pin 85 in the present embodiment is six, and six combined type pins 85 are evenly distributed in rotating shaft 86.
Referring to Fig. 5-Fig. 6, Fig. 5 is the plan structure schematic diagram of case card bolt head, Fig. 6 is the structural representation of the B-B in Fig. 5, four bayonet locks 892 in spanner 89 first insert in four neutral gears of head 101 of case card bolt, moving beam 4 further declines, now spanner 89 has supported the head 101 of firm case card bolt, spanner 89 no longer declines, and the first Compress Spring 82 being arranged between locking wrench 8 and motor output shaft 71 is gradually reduced, to offset displacement difference, when lift cylinder 5 is down to desired location, moving beam 4 down maneuvers also stop thereupon.
Referring to Fig. 7, for having completed in the utility model, initially fasten case card bolt 10 states.
Referring to Fig. 8, for the locking case card bolt 10 state partial structurtes schematic diagrames in the utility model, when inductance type switch 9 detects sleeve pipe 83 upper circular boss 832 edge, to PLC, send signal, the tail end 102 that shows case card bolt has supported firm swage sandbox, air motor 7 is rotated further 2-3 and carries out time delay second, then stops operating.
The effect of time delay is: when case card bolt 10 supports firm swage sandbox; cannot continue rotation declines; now rotating shaft 86 is forced to stop operating; and make sleeve pipe 83 with rotating shaft 86 in relative rotation status; steel ball 851 is forced to extrude the hemispherical cancave cambered surface 861 of rotating shaft 86; again under the effect of the second Compress Spring 852; next cancave cambered surface 861 of jacking; thereby the intermittent moment of torsion of countershaft 86 output; with further clamping screw; due to the second Compress Spring 852 compressibilities, each parts such as locking wrench 8 and air motor 7 have also been played to the effect of overload protection.
During work, the original state of device is: the moving beam 4 being connected with lift cylinder 5 remains on a high position, and the locking wrench 8 being connected with air motor 7 is rotation status not.
When be loaded with the transport trolley of swage sandbox be pushed to device under time, now case card bolt 10 is in unscrewing state, lift cylinder 5 starts to drive moving beam 4 to decline, guide post 6 plays and leads and maintain the effect that moving beam 4 steadily declines in this process, in the process declining, first spanner 89 inserts in head 101 neutral gears of case card bolt, moving beam 4 further declines, now spanner 89 has supported the head 101 of firm case card bolt, no longer decline, and the first Compress Spring 82 being arranged between locking wrench 8 and motor output shaft 71 is gradually reduced, to offset displacement difference, when lift cylinder 5 is down to desired location, moving beam 4 down maneuvers also stop thereupon, now, completed and initially fastened case card bolt 10 states.
And then, air motor 7 starts, drive locking wrench 8 to rotate, thereby case card bolt 10 is applied to moment of torsion, the rotation that has realized case card bolt 10 process that thereupon declines, in this course, the first Compress Spring 82 discharges compressive tension gradually, and promotion locking wrench 8 declines with the decline of case card bolt 10, thereby has guaranteed both synchronisms in height displacement, in the process that guarantees to decline in rotation at clamping screw 10, can not throw off with spanner 89.
When inductance type switch 9 detects sleeve pipe 83 upper circular boss 832 edge, to PLC, send signal, represent that the tail end 102 of case card bolt has supported firm swage sandbox, air motor 7 is rotated further 2-3 and carries out time delay second, then stops operating.
When time-lag action finishes, air motor 7 stops operating, and lift cylinder 5 drives moving beam 4 to rise to a high position, is repositioned to original state, waits for that next transport trolley enters, and repeats above-mentioned action case card bolt 10 is next time locked.
In the present embodiment, motor output shaft 71 and sleeve pipe 83 in locking wrench 8 are connected for cylinder plug-in type, rotating shaft 86 and sleeve pipe 83 are connected for cylinder plug-in type, said " connection of cylinder plug-in type " refers to that motor output shaft 71 is column types, sleeve pipe 83 is made into circular port, the slightly larger in diameter of this circular port is in the diameter of motor output shaft 71, motor output shaft inserts in circular port, under the effect of external force, both just can insert and stretch out, be cylinder plug-in type and connect, motor output shaft 71 is also the same with the connected mode of locking wrench 8.
In the utility model; the connected mode of end cap 87 and sleeve pipe 83; the connected mode of moment of torsion handwheel 84 and sleeve pipe 83; be not limited to the connected mode of screw and screw thread; the quantity of combined type pin 85 and whole locking device can be selected according to the structure of transport trolley and actual production status, carries out the simple change of connected mode, quantity and simple structure and structure all in the protection domain of the utility model patent.
